British media reported that the fee for the 24-year-old would be around 75 million pounds ($96.68 million), making him the club’s second most expensive signing after last year’s world record deal for French midfielder Paul Pogba.

Lukaku, who also attracted interest from former club Chelsea, scored 25 league goals in 37 matches for Everton in the last campaign, four behind Tottenham Hotspur’s Golden Boot-winning striker Harry Kane.

The striker, who has also scored 20 goals for Belgium, rejected a new contract at Everton in March and will reunite with United manager Jose Mourinho, under whom he served at Chelsea.
